Basics of Contains ( ) expression
The CONTAINS() function is a critical component in the toolkit of an AppSheet app developer. It serves as a simple yet powerful search tool that checks if a given text string includes a specified substring. This function is instrumental in refining user interactions, enhancing data filtering, and customizing app behavior based on specific text conditions. The basic syntax of the CONTAINS() function is as follows: CONTAINS(text_to_search, substring_to_find) text_to_search: The text within which you want to search for the substring. substring_to_find: The specific string you're looking to find within the main text. The function returns
Using OCR in Appsheet
Optical Character Recognition (OCR) technology has revolutionized the way we interact with digital data, and AppSheet's OCRTEXT function stands at the forefront of this innovation. This powerful tool enables AppSheet applications to extract text from images, transforming image-based data into actionable, searchable text. OCRTEXT allows developers to seamlessly integrate OCR capabilities into their AppSheet applications. By analyzing images for recognizable text, OCRTEXT converts these images into a string of text that can be used within the app for various purposes, from data entry to content analysis. The versatility of OCRTEXT opens up numerous
Switch ( ) function
The SWITCH() function in AppSheet is a powerful tool that simplifies decision-making processes in your applications. Unlike traditional IF() statements that can get complex and hard to manage with multiple conditions, SWITCH() offers a cleaner, more readable alternative. This function evaluates a given expression and matches its result to a list of cases, returning the corresponding value for the first matching case. Using the SWITCH() function in AppSheet is straightforward. Here’s a simple syntax to get you started: SWITCH(expression, case1, value1, case2, value2, ..., default_value) expression: The value or expression you want to evaluate.
